Apparently life does not imitate art. Leonardo DiCaprio was so convincing in his role as Jordan Belfort in “The Wolf of Wall Street” — the Golden Globes thought so — that he has fans believing he did coke in real life. But, at a GG party over the weekend, Leo overheard somebody say “I bet playing that role put you off cocaine forever.” Leo replied: “I’ve never done it in real life.” Notice he didn’t say he’s never smoked pot in real life. Had he done that, half of New York and L.A. wouldn’t have stopped laughing for weeks.
